NITED STATES GEORGE L. BELANGER, OF CHICAGO, ILLINOIS.

COMBINATION LOCK.

Application filed September 8, 1921.

To all whom it may concern:

Be it known that I, GEORGE L. BELANGER, a citizen of the United States, residing at Chicago, in the count-y of Cook and State of Illinois, have invented new and useful Improvements in Combination Locks, of which the following is a specification.

This invention relates to combination locks adapted for use upon automobiles and has for its object to provide such a look for use between the carbureter and intake manifold of the engine.

A further object of the invention is to provide such a device which may be operated from the dashboard of the automobile without the necessity of the operator raising the hood of the machine.

A further object of the invention is to provide a device of this character whereby the intake of gasoline may be prevented, thereby eliminating the possibility of operating the machine by unauthorized persons.

A further objectof the invention is to provide a combination lock for the intake manifold of a gasoline engine, which is extremely simple in construction, strong, durable, and convenient in use.

Other objects and advantages of the invention will be apparent from the following description:

deferring to the drawings, wherein like numerals are employed to designate like parts throughout,

Figure 1, is a side elevation of the apparatus applied to an automobile,

Figure 2, is a plan view of the valve plate and associated elements,

Figure 3, is a central, vertical longitudinal sectional view taken on line 22 of Figure 2,

Figure 4, is a transverse vertical sectional view taken on line 33 of Figure 3, and.

Figure 5, is a horizontal sectional view through the device.

Referring to the drawings, the numeral 5 designates the carbureter of an internal combustion engine, and 6 the intake manifold thereof. Bolted between the flanges of the carbureter and intake manifold is a valve plate 7, having an extension 8. Plate 7 is provided with an opening 9, which registers with the gas passages of the carbureter and manifold. Rotatably mounted within the valve plate 7 and the extension 8 is a shaft 10. This shaft extends across the opening 9 and has secured thereto a disk 11,

Serial No. 499,242.

which when turned in one position will entirely close the opening 9. The shaft 10 has a plurality of notches 12, adapted to co-act with looking elements, to be described.

The extension 8 of the valve plate 7 is provided with a plurality of cavities 13 adapted for the reception of combination locking elements 14. The locking elements 14 have a notch in one side adapted to register with the notches in the shaft 10. It will be obvious that when all of the notches are brought into registration with the notches in the shaft, rotation may then be imparted to the disk 11. The means for causing the rotation of the shaft 10 may be a crank arm 15 securely fastened to the shaft and operated by a rod 16. This rod 16 may be operated either from the dash board or may be connected with the regular carbureter throttle valve rod. The elements 14 are held within the cavities 13 by plugs 17, which have screw-threaded engagement with the walls of the cavity. Spring dctents 18 are carried by the plugs 17 and operate within cavities 19 formed in the lower face of the elements 14. In this particular form of the invention I have employed ten of these cavities 19.

Means are employed for rotating the elements 14 for bringing their notches into registration with the notches in the shaft 10, such means comprising U-shaped members 20 having extensions 21 which have a plurality of ribs formed thereon for engagement with ribbed recesses in the elements 14, this to prevent the elements 14 and 20 from turning with relation to each other. Pivotally mounted within the U-shaped elements 20 are balls 22 which have engagement with U-shaped members 23, the members 20, 22 and 23 forming a universal joint. The elements 23 are formed upon tubes 24 having rods 25 slidably engaged therewith. These rods 25 are prevented from turning with relation to the tubes 24 by pins operating within slots 27 formed in said rods. The free ends of the rods 25 carry U-shaped heads 28, which are pivotally connected with balls 29 in turn pivotally mounted within U-shaped members 30. As will be seen the members 28, 29 and 30 also form a universal joint. The elements 30 are carried by short shafts 31, said shafts in turn carrying knobs 32, the heads of which are knurled.

As shown by the drawing there has been employed four sets of combination elements and associated operating means, but it will be obvious that'this} number may be varied at will. As shown in Figure 1, one set of I impart'rotation of the elements through the medium of the tubes 24, rods 25 and associated universal joints. Each element 14 may carry a different combination. this combination' depending upon the position of the elements 20 with relation thereto. The operator may determine this position by rotating the elements 14 slowly to thereby force the spring detents 18 out of the notches 19 one by one, until the desired number has been reached. This same operation is performed upon the other elements 14 so that all of the notches may be brought into registration. then be imparted to the shaft 10, by the rods 16, as before mentioned. WVhen the operator desiresto lock the gas line he rotates the shaft 10 to the desired position, and then rotates each of the knobs 32 a short turn.-

VVhen it is desired tochange .the combination the operator lifts the elements 20 and extensions 21' from the recess of the elements 14 and gives each a partial turn to correspond with the combination that he desires and then replaces suchextensions 21 into the recesses of the elements 14. The ribbed re- Rotation may same, but 'it is also to be understood that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having described my invention what I claim is:

A look for use on internal combustion engines comprising a body adapted to be arranged between the carbureter and an intake manifold and having a lateral extension, a controlvalve arranged in said body and having a shaft provided with spaced notches, short separate tubular locking elements arranged in said extension and having notches adapted for registration with said first named notches whereby saidshaft may be turned, the tubular locking elements having internal longitudinal ribs, actuating members having stems received in said look.- ing elements and having longitudinal ribs engaged with said first named ribs, each stem being separately actuated and separately adjustable with respect to the co-operating locking element. and plugs threaded in said extension and rotatably supporting the locking elements, there being means between the locking elements and the plugs to hold the locking elements in said positions.

In testimonv whereof I afiix my signature.

GEORGE L. BELANGER...
